SortArrayDbl Description
SortArrayDbl(
double *Int_ArrayDbl,
long Int_Count

This function can sort an array of double values. The sorting is ascending.
Int_Count parameter is the position of the desired value (0 for the first position).
Parameters
double *Int_ArrayDbl A name of the array.
long Int_Count Number of bytes.
double data[1000];
int size;
double median;
char text[64];
ScanObjects();
size = Get_NumObjects(FIELD_LAST, 0);
if (size>0)
{
Get_ObjectFeatureData("Area", data, FIELD_LAST, 0);
SortArrayDbl(data, size);
median = data[size/2];
sprintf(text, "Median is: %f","median");
WaitText(3, text);
}
